Terry,I'm putting in a shower stall in a remodled bathroom and I had an older POWERS REGULATOR faucet in my pile of GONNA USE IT SOMEDAY stuff.Its new and in the box but the instructions say nothing about mounting it. They explain how to install it through the wall and everything but I can't figure out how to attach it to the wall behind the shower.It looks like they let the water pipes hold it in place but I'm kinda nervous about that.Have you seen this before? I haven't finished the wall yet so I'm not in TOO deep.... But I'd like to know where to put the next stud in reference to the mixer. Any advice would be appreciated.Thanks Again,
